EWiPRQVEiVlENT EN HORSE-POWERS.

To all 'whom it may concern:

Be it known that we, THEOPHILUS HAR- RrsoN and WILLIAM C. BUCHANAN, of Belleville, in the county ot St. Clair and State of Illinois, have invented a new and Improved Horse-Lower; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the saine, reference being had to the accompanying drawing forming part of this speciiication, in which- Figure l represents a vertical longitudinal section oi' our improved horse-power taken on the 'plane oi' the line x Fig. 2. Fig. 2 is a pian or top view oi' .the saine.

Similar letters of reference indicate correspondin g parts.

rlhe object of this invention is to construct a mounted horse-power which has its powerconveying shaft low enough to connect directly with the tumbling-rod without requiring inclined or other inconvenient connections, and where the said conveying-shaft and appendages can be elevated sufficiently high from the ground to clear stumps and stones while the machine is being moved to or from the place of operation. The most valid objections to the horse-powers now in use are thereby overcome. rIhe invention consists in the amilication ot various new features and combinations, as hereinafter more fully described.

A in the drawing represent-s the frame ot` our horse-power mounted on the axles B and supporting the east-iron bed-plate G. rIhis traine consists of two large sills, a a, iirinly bolted to the front bolster I) and rear axle B and properly braced. D is an extra frame, which carries the bevel-wheel c and a pinion, d, and a horizontal shaft, E. This frame we call the bevel-wheel frame.77 Itis suspended from the main frame A ot' the power by pcculiarlyshaped bolts F Il, which. hold it in position and permit it also to be vertically adjusted. The horizontal bevel-pinion sha-it Ii is, by this suspended trame, held in a true line with the tumbling-rod, thus avoiding angle connections; at the same time this frame D can. be raised from the ground so as to malte the power transportable. These are obvious advantages. During transportation the levers, rods, braces, Sto., can be placed on the axles, immediatelyv under the bed-plate C, between the sills, and all carries easily, wit-hout additional cost to the power, thus saving the use of an extra wagon, or expense in making holsters, or other arrangements for carrying these articles above the main wheels. G is the annular drive-wheeLtoothed, to rotate three pinions, c e. These pinions are, respectively, mounted upon spur-wheels, g, which all gear into` one pinion, L, in the center of the power. All these wheels and pinions are supported on the solid cast-iron bed-plate C. The center pinion 71., hung on an upright shaft, i, has a central hole, of which the lower portion is bored out round to keep the pinion in its proper position on the shaft and relatively right to the spurwheels that drive it, at the same time being loose on the sha-ft to permit the adjustability of shaft up and down, while the upper part ot' said hole is made square for the purpose of receiving the square upper end of the shaft i and driving it when in position Jfor running. This upper part ofthe hole may be notched or made in any other manner that will answer the purpose of driving the shaft when thrown in gear.

The construction of the power, as far as it relates to the upper gearing G, e, g, and h, does not vary 'from other triple-gear powers, except as to the hole in.pinion. 0n the lower plate of the adjustable frame D are boxes for the shait E. To the bevel-wheel c is keyed the lower end of the shaft i. This sha-it is guided in a frog-shaped casting, j, which projects froin the lower plate ot' D, as shown in Fig. l. lllhe bolts I?, which we call suspending-bolts, have their upper port-ions inade larger than the lower, so that the nuts k, near their centers, when unscrewed, will readily drop down to allow the raising of the frame D. TWhen the nuts are screwed to the bolts F, up against guide-tubes or nibs l, which project from the bed-plate C, the frame D is# locked and cannot be raised. Another inanner oi' making the frame D and upright-shaft t' and box would be to extend a series ot arms from this frame D above the arm oil bed- Aplate, to which could be attached a journalbox immediately under or above the center pinion h, and said pinion could be tightly keyed to the shaft, and in the adjustment of raising and lowering all these parts the frame D, upright shaft i., and center pinion h, with box and supporting-arms,

could all be movd wear and loss of a Y H4555 up or down together. While, as in Fig. l, the frame D is lowered for operating the machine, the shaft E is brought down near enough totlie ground to permit the direct coupling to the tumbling-rod, thus obviating the necessity ot' angles, and the consequent power on couplings and boxes. The frame D, with horizontal shaft E and perpendicularly-adjustable shaft i, is so arranged that when the. power is to be used it is tirmly braced and secured to the ground in the ordinary way. Then the long bolt, passing under the sills, and supporting the trame D in its elevated position, is removed, which permits the lowering otl the frame D until the bevel-pinion sha-ft E is on a true line with the tumbling-rod. Then the nuts it, which are loose on the bolts F, are screwed up hard and tight against the nibs or projections that extend down from the bed-plate to near the bottom ot the sills. By tightening these. nuts the frame D is held securely down. The bolts F, it will be seen, serve to hold the entire power firmly together, at the same time being adjustable to raise and lower the frame D. They have, therefore, three distinct uses-Just, holding the frame D securely down; second, allowing the raising ofthe frame and acting as guides; third, holding' the entire power together. The bed-plate U and its construction is to be considered in connection with the bolts. Vertical nibs m, on the bed-plate, project upward to sustain the circular plate 'n above the gearin Other nibs, l, project down to near the sills. These nibs or projections are tubular, and in line to constitute guides for the bolts F. They are cast solid to the bed-plate, and make the whole power very solid and rigid. l/Vhile these nibs, we think, are the best means for the said purpose, yet' a plate might be cast, or an additional or second bed-plate made and bolted on the bottomhot' sills, through which the bolts might pass. This, however, adds extra pieces and work without being as good and firm as the nibs.

When the power is to be transported the nuts 7e are unscrewed and dropped down over the bolts, and the frameD is raised and fastened up between the sills.

We are aware that frames with wheels have been made, and made adjustable and staked to the ground, and fastened also by complex arrangements to the power; but our im provement consists in suspending the adjustable frame from the power without separately connecting it with the ground.

In this power, constructed as it is, we have ample room to carry levers, rods, braces, jacks, Sto., under the bed-plate and between the sills. All other portable powers have devices, bolsters, te., arranged above the main wheel, which arrangements are complex, troublesome, and expensive. They also make the powers top-heavy and more lia-ble to upset in traveling over uneven roads, while our placing these heavy articles right on the axles makes it almost impossible to upset the power.

The devices and holsters on other powers Vare expensive because they are extra work and material added to the powers, while on ours all these levers, rods, Ste., rest on the axles, without a particle of expense or any need of adjustable holsters, 821e. These standards, holsters, &c., are also troublesome because they must be put on and o't't' each time the powers are moved and set. The frame D, when raised, can be held up in suitable manner either by pins, bolts, levers, or other devices.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. The vertieallyadjustable bevel-wheel frame D7 made substantially in the manner herein shown and described, and applied to a horse-power in the manner specified.

2. The suspending-bolts F, with their upper lengths m ade larger' than the lower lengths, so that the threads on the upper lengths will require nuts large enough to pass loose over the lower lengths, as set forth.

3.' The bed-plate C of the power, provided with projecting nibs Zand m, that extend downwardly and upwardly, and serve as guides for the bolts F, substantially as and for the purposes set forth.

4. The center pinion L, made with one part of the hole round and the other portion square or notched, to be thrown in or out of gear, as described.

5. The upright shaft fi, keyed tight to the bevel-wheel c in the frame D, and loosein the center pinion 71, above, and squared at the upper end, substantially as and for the purposes set forth.
